Abstract: Propylene polymerization titanium–magnesium catalysts in the presence of ethers are synthesized. It is shown that aliphatic ethers and 1.1-diethers are participated in the formation of magnesium chloride although they are not contained in catalysts. Aromatic ethers (except methyl phenyl ether) are ineffective in the MgCl2 formation. Subsequent adding of the phthalate (DBP/Mg = 0.05 mol) lead to the synthesis of the phtalate titanium–magnesium catalyst which in the case of aliphatic ethers and 1.1-diethers have catalytic properties higher than the titanium–magnesium catalyst for comparison (DBP/Mg = 0.05 mol) and close ones (for some ethers) to the standard titanium–magnesium catalysts (DBP/Mg = 0.2 mol). Comparative analysis of the composition of phthalate titanium–magnesium catalysts prepared using ethers or ketones and X-ray data indicate a close size of MgCl2 crystallites in both cases. The composition of titanium–magnesium catalysts synthesized in the presence of ethers is consistent with the distribution of dimeric TiCl4 complexes alternating with chlorine vacancies (…□TiTi□TiTi…) on the lateral cuts 104.
